IMPROVIE!:MIEINT. IN DETACHABLE HORSESHOE-CALKS.

The Schedule referred to in theseLetters Patentand making part of the name.

To all whom 'it 'may concern Be it known that I, PERLE; LAFLIN, of Warren,

county of NVorcester, and Commonwealth of-A Massachusetts, have invented certain new and useful Imlproveniente in Detachi ble Horseshoe-Callie; and I doVA hereby declare that the following is a full,lclear, and

exactdescription of the saine, reference being had to -the accompanying drawings, vforming a lpart of.,l this cured to the feet of draught-animals, as will be hereafter explained.

In the drawings- A represents a horseshoe, to which one of my` detachable calks is applied.

The calks a (t are secured tothe ends b b oi' the clamp-plate B, from the inner edge of which projects `a lip, c, which clasps the inner side of the shoe, alsV fully shown inthe drawings, while from the outer edge of the plate projects a right-angled set-screw, supporting piece d, through the upright part of 'which is screwedthe set-bolt or screw O, the inner end oi' lthe screw C being provided with, o r swivelled to a ciamping-plate, e, which is forced against the outer edge of the shoe, when the calk is applied thereto, as clearly indicated in iig. 3 of the drawings.

The calksa may be made fof any desired form, and any number may be formed on or secured to the plate B, which practice may prove 'necessary or proper;

The calks may be applied to both sides ofthe shoe,

if desired.

pursued, or theteam driven with perfect safety.i`

' It will. be noticed that a recess or groove, '1, is formed in the upper side ofthe clamp-plate B, for the reception of the heads 2 of the nails by which the shoe' is secured to the-foot of the animal.

As the upperledge's of the clamping-plate e and lip c are turned in, they lap overthe upper edges of' the shoe, when applied as shown in iig. 3, therebyinsuring a very firm and secure attachment of the -plate B, with its calk or calks c, to the shoe.- I The advantages of my ,i 'vention will be readily appreciated, since they can be applied .to the shoes in a few minutes, .without the use-of tools, except a small `wrench to'turn the set-screw C with.

It often happens lthataperson travelling is obliged 'to stopuntil his horse is newly shod, owing tothe sudden formation of ice.' The same is true in relation to` teams employed in drawing loads. Bymy in'vention. it will be seen that the ditculty is cbviated, since .the'detachable calks canbe applied, and the ljourneyl The lip c and theclamping-plate e may be so made that theywill t equally well thick vand thinzsho'es',-or

new shoesas well as those which have been worn down thin. l

Having describedfmy improved detachable horseshoe-calli, v vVVh'at I claim therein as new and -of my invention,` and desire tov-'secure by Letters Patent, is

l. The combination,-with clamp-plate B' and4 setscrew C, of the Aswivell-ed plate e, substantially as and for the purposes set forth. y

2. The detachable calk B, constructed and secured` to the shoe in the manner and for the purposes set forth.
